:HAYSTACKER-ANCIHORING DEVICE.

' This inventicn relates to improvements in the construction of hay stackers of the type described and claimed in United States reissue Letters Patent No. 151558, granted to me on July 17, 1923.

Instackers of this type the hay is raised and thrown onto the stack by power derived froth horses or from some tractive device "such as a tractor or an automobile. The horse or tractor isf'hitched to one end of a rope whose other end is attached to the stacker arihs When su'fiici'erit force is exerted on the rope, the stacker 'ar'ins wil. be raisedhndthe hay elevated and deposited on the "stack. since it requires a strong pull to raise the hay, there will be a strong force tending to move the stacker from 'th'e pos'ition that it shouiadceu y. Immethat the stacker shall remain stationary it "iniist be anehored in some way, as by stakes driven int-. the groiind. This has not proven to be satisfactfiry as the stakes beco'lrie loose and its it involves considerable labor. As the stacker 'is pieced up against a 'stack o'f 'ha'y, it seems that the most logical thing to do would be'to anchor the-stacker to the liay'stack and this is what I propose to do. invention, briefly described, consists in attaching to the end of the stacker an av extension inthe forrn ofa brace, which extension is. designed to project 'underneath the stack in such 'a manner that the hay will kee it irorhfmoving. This'brace is so constructed that it forms with the stacker a stress triangle which produces rigid brace structure and .which is so designed and assembled that the members of which 'it isc'einposed can be'readily removed from underneath thestack after the latter is coin r'll t d- Ely-inv t n can b mes 9 7 X 'plained' and willbe most-"readily understejod .whenQreference is hadfto the accjo'inpanying drawing in which it-has beenillu'strat'ed and inwhich't My H m g- .11 31 d .l ffiti libf S 1 l' hd ing th br eim mb r Jaaee iih 'j i .pb 'it Qi m d 'ne thih ,steel V Fig.2 'isfa p'l'an view looking downwardly as. el ates. f i'e:izert a w i st k r m -1 3 bre sh W I g llO 'th rrw' ae. .c ii ct d and sh -Wing. al o .lidw thestack'er framemevesthe bracenien bers and ;.m m tp. fmga is oif fa pin' 28. 7 Fit will 'newhe vident levee tracewer th it a l v were triangle "that is rigid Replication filed June 15, i925.

" Fig. 4 is a detail view showing the man- ,ner in Which the brace members are Connected toe'ach other.

Numerals 1 and 2 represent the base membersof a stacker and 3 and 4 the vertical posts to which the stacker arms 5 and 6 .are pivoted. To the ends of the stacker its upper end connected to the stacker arms 5 and 6 by means of links l3. A rope M is connected 'tothe A frame nearits vertex and passes overfthje pulleys 15, 1' 6 and 17. The horses airehi'tchedto the free end 18 of the rope. Vvhensuflicie'nt force isexerted on the rope, the stacker 'arr'n's will 'be raised and the hay will be deposited on the. stack. The stacker illustrated describeclinere- 1y shows the essential parts of a stacker mechanism of the type to which my invention appertains and is intended merely to illustrate my nvention and g to show the broad combination asnry anchoring device may be jiised in connection with any stacker of this type.

My brace wisprises two bars, 19 and 20, which 'are' connected to each other "and to the base members '1 and 2"in the manner which I will now describe. The bar 19 has a steel plate 21 secured to each side extendlbeyoiid the end 6f the-bar "ans s ss d time which they are *cbnne t d by that when the stacker is operated, the horses exert a pull on the rope 14 whose direction and intensity may be represented by the arrow F. This force may be resolved into two components represented .by arrows P and L which are respectively perpendicular and longitudinal of the frame member 1 and brace member 19. The force P tends to move the stacker to the side and the force L tends to move it longitudinally. Both of these forces are resisted by the braces 19 and 20. The diagonal brace member 20 being held against the ground by the superposed hay cannot move in the direction of arrows L or P, while the bar 19- cannot move in the direction of the arrow L. The stacker is therefore securely anchored. As the stacker, arms with the attached stacker head move into vertical position for the purpose of discharging the hay onto the stack, it must be prevented from passing beyond the vertical so far that it will not return and this is guarded against by a rope 30,, one end of which is attached to the stacker frame and the other to the stacker head. When the stacker so that the base members will pivot it is stopped quite "suddenly with the result that the momentum of theparts exert sufficient force to raise the front end of the stacker so thatthe base member will pivot about their rear ends and move from the full line to the dotted line position (Fig. 3) and back again. This periodic up and down movement keeps the braces from becoming too solidly clamped between the'hay and the ground so that they maybe more readily .withdrawn. When the stack is finished and the stacker is tobe removed, the pins 23 and i 28 are first withdrawn after which the stacker may bemoved-to anyplace desired. The brace bar 20 is then removed by a straight pull which causes it to become separated from bar 19 in the manner shown in Fig: 4. The brace bar 19 may now be removed by a straight pull.

I want to call particular attention to the fact that brace bars 19 and 20 together-with the transverse bar 29, forms a triangle that is rigid and strong. Thelfact that the base member 2 extends slightly to the rearof the bar 29 should notbe construed as a 'sufiicient departure from a triangle to make thatterm inaccurate as the effect is practically the same. The base member .2 might'be terminated exactly to the rear of the bar 19, but this wouldmake it necessary to dispense with the plate 27. I also desire to call attention to the factthat the bars "19 and 20 are so connected 'to each other that. they can be readily separated, in the manner shown inFig. 4:. Thismakes it possible to remove them from\, underneath the stack" which could not be. done if theywere' not connected -in such a manner that this were possible.

rigid structure that, results frornthe arlatter a triangle;
